Study On Correlation Between Landscape Ecological Risk And The High Quality Development In Different Watersheds Of Gansu Province

How to deal with the problem of landscape fragmentation caused by human interference to nature and realize the ecological protection and high-quality development of the basin is an urgent problem to be solved.By measuring the landscape ecological risk and high quality development level of different basins in Gansu province,this paper explores the correlation between landscape ecological risk and high quality development level of different basins,in order to provide reference for the ecological protection and high quality development in different basins of Gansu province.The results show that:(1)The landscape ecological risk and quality development level of different river basins in Gansu Province are significantly different.The landscape ecological risk level of inland river basin is higher,while that of Yangtze River Basin and Yellow River Basin are at a medium level.The high quality development level also shows obvious regional differences,with the Yellow River Basin > Inland River Basin > Yangtze River Basin.(2)The global correlation analysis of landscape ecological risk and high quality development level in different river basins in Gansu Province shows that: the spatial distribution of landscape ecological risk and high quality development level in the Yellow River Basin and Inland River Basin is positive,but in the Yangtze River Basin,the spatial relationship between landscape ecological risk and high quality development level is negative.(3)The local autocorrelation analysis of landscape ecological risk and high quality development level in different river basins in Gansu Province showed that the low-riskhigh level development area of the Yellow River Basin was mainly distributed in Huangshui rivers;The Gansu section of the Yangtze River Basin is distributed in the West Han River rivers.The low-high area of inland river basin is distributed in the Mustang rivers.(4)The distribution of high risk and low level development in different basins in Gansu Province is as follows: the Yellow River Basin is mainly distributed in Weihe rivers;The Yangtze River Basin is distributed in Bailong rivers.The Inland River Basin is mainly distributed in Shiyang rivers.In this area,vegetation coverage should be increased to reduce ecological risks and improve disposable income to promote highquality development of the basin.(5)The distribution of high-risk and high-level development areas in different basins in Gansu Province is as follows: the Yellow River basin is mainly distributed in Datong rivers;The Yangtze River Basin is distributed in Gongba rivers.The Inland River Basin is mainly distributed in Danghe rivers.The main goal is to reduce landscape ecological risk in this area.(6)The distribution of low-risk and low-level development areas in different basins in Gansu Province is as follows: the Yellow River Basin is mainly distributed in the Zuli rivers;The Yangtze River Basin is distributed in the Red rivers.The Inland river basin is mainly distributed in Gulang rivers.For this region,we should not only pay attention to the improvement of high-quality development level of,but also ensure that the ecological risk of this region is at a low level.
